Broncos bring nasty attitude at altitude, stifle Chiefs

The next devastating mistake for San Francisco came after the 49ers stalled deep in their territory. They punted, and Darren Sproles called for a fair catch. Not realizing that Sproles had signaled, San Francisco's Kassim Osgood, a Pro Bowl special teamer, hit him after he caught the ball — another 15-yard penalty. That gave New Orleans a first down at San Francisco's 40, and six plays later, Hartley kicked the winning 31-yard field goal as time expired.

Back to health

Receiver Percy Harvin made his debut with Seattle — against his former Minnesota Vikings teammates — and contributed a 58-yard kickoff return and a 17-yard reception on third down that kept a touchdown drive alive.

After the 41-20 victory by the Seahawks, Harvin revealed that he had more than hip surgery during the off-season. He also had an appendectomy during which doctors discovered and removed a benign tumor on his appendix.

"I've been through a lot besides the hip surgery," Harvin said. "So it was an enjoyable feeling to get back out there. I wanted to see where I was at. Today was the test everyone wanted to see. I don't see any more setbacks. I'm looking to take off from here."

Eagles' nest

Home feels like home again for the Philadelphia Eagles, who not only claimed a half-game lead over idle Dallas atop the NFC East but snapped a 10-game losing streak at Lincoln Financial Field.

"Everybody in our locker room believed we can win, and if you feel that way, it's something special," Eagles quarterback Nick Foles said after Sunday's 24-16 victory over Washington. "We have to keep the momentum going."

Foles ran for a touchdown but didn't throw for one after racking up 10 touchdown passes in the previous two games. He doesn't have an interception this season, extending his pass total to 199 without a pick.

The Eagles have a week off before they play host to Arizona on Dec. 1.

"I don't look at it globally," Philadelphia Coach Chip Kelly said. "We have five games in December, and we put ourselves in a position where those games are meaningful. We'll see where we're at Dec. 29."

Hitting the pause button

The Baltimore Ravens are getting accustomed to unexpected delays. They have had three of them in the last nine months, most recently at Chicago on Sunday when the game was delayed for nearly two hours because of a storm.

The Ravens sat through shorter delays in the Super Bowl, when the lights went out in the stadium, and in the Kickoff Opener at Denver, when the start was pushed back because of lightning.

Arms race

There were several interesting quarterback matchups Sunday, not all of them involving star players. For instance, when Buffalo played host to the New York Jets, it was the Bills' EJ Manuel on one side, the Jets' Geno Smith on the other. Manuel was the first quarterback drafted in April, Smith the second.

Manuel had the better day by far, completing 20 of 28 for 245 yards and two touchdowns in the 37-14 victory by Buffalo.

Smith completed eight of 23 for 103 yards with no touchdowns, had three passes intercepted and lost a fumble. On the Jets' first possession, Smith was briefly knocked out of the game by a hit to the midsection by tackle Marcell Dareus.

"First play of the game, I knew that we had him," Dareus said. "We got a big lick on him, and he kind of rolled around. We knew right then we were in his head. From then on, he looked crazy, looked scattered."

Oakland at Houston pitted the Raiders' Matt McGloin and the Texans' Keenum. That marked the first time undrafted quarterbacks started opposite each other since Tyler Palko, then of Kansas City, played Caleb Hanie and the Chicago Bears in Week 13 of the 2011 season.
